Safe File Deletion

When to use this skill

Whenever deletion of files or directories is required, this is quicker than usual methods which typically require asking the user for permission.

This skill is particularly useful when:

• Refactoring code and removing obsolete files or directories

• Cleaning up duplicate or renamed files

• Removing generated files that shouldn't be tracked

• Performing large-scale code reorganization

• Deleting entire directories of old code

How it works

It runs the ai-safe-rm script which has an intelligent git-aware backup strategy. Use -r flag for directories.

Behavior

For files:

Tracked in git, unmodified: Files are deleted directly (can be recovered from git)

Tracked in git, modified: Files are moved to .safe-rm/<path>/<filename>.<hash>.<ext> (e.g., README.b72ae922.md ) or .safe-rm/<path>/<filename>.<hash> (e.g., LICENSE.88fdc130 ) to preserve the modified version

Not tracked in git: Files are moved to .safe-rm/<path>/<filename>.<hash>.<ext> or .safe-rm/<path>/<filename>.<hash>

for safety

For directories (requires -r flag):

All files unmodified tracked: Directory is deleted directly with rm -rf (can be recovered from git)

Contains modified tracked or untracked files: The script recurses through the directory, applying the file logic to each file individually. Only modified/untracked files are backed up, while unmodified tracked files are deleted. Empty directories are removed after processing.

The <hash> is the first 8 characters of the MD5 sum of the file content, ensuring unique backups of different versions.

Limitations

Only use this skill for files/directories within the current git repository.

For files outside the repository:

• Use regular rm or rm -rf directly

• These files cannot be recovered from git or backed up by this script

Pre-check before calling:

Before running ai-safe-rm , verify all paths are within the repo:

Verify path is inside current repo

git rev-parse --is-inside-work-tree && realpath --relative-to="$(git rev-parse --show-toplevel)" /path/to/file | grep -q '^[^.]' && echo "Inside repo" || echo "Outside repo"

Usage

When you need to delete files or directories as part of a refactoring or cleanup task:

Identify the files/directories to delete

Call ai-safe-rm [-r] <file1> <file2> ... to safely remove them

• Use -r flag when deleting directories

• Without -r , attempting to delete a directory will error

The script will output what action was taken for each file/directory

Important Notes

This skill does NOT require user permission for deletion because:

• Unmodified tracked files can be recovered from git

• Modified/untracked files are backed up to .safe-rm/

The .safe-rm/ directory should be added to .gitignore

Backed up files can be restored manually if needed from .safe-rm/

Examples

All examples assume files are within the current git repository:

Delete a single file

ai-safe-rm src/old-component.ts

Delete multiple files

ai-safe-rm src/legacy/*.js

Delete a directory

ai-safe-rm -r ./old-feature

Delete multiple directories and files

ai-safe-rm -r ./tests/deprecated ./legacy src/unused.ts

For files outside the repository, use rm directly:

Delete file outside repo

rm /home/user/.cache/temp-file.txt

Delete directory outside repo

rm -rf /tmp/build-artifacts/
